Battery on iphone 3g s drains very fast.

Coming from an iPhone 2G, I can definitely tell the difference in battery life. I used to be able to go all day or more with light usage and around 4 or 5 hours of usage with 10+ hours of standby. It doesn't seem that's the case any more. I do think the percentage meter makes me more worried about it. But anyway, here are my statistics. 3G On, WiFi Off, Location Services On, Push Off (Fetch Every Hour) and Auto Adjust for the screen's brightness. 81% battery life, 47 minute usage, 5 hours and 35 minutes standby. This is for today, I charged it in the morning. Is it normal?
Theres a problem with the 3.0 Firmware see here https://forums.macrumors.com/showthread.php?p=7906348#post7906348
I've had to go back to 2.2.1 on my 2g phone. (and now no battery issues, before i was getting about 3-4 hours) Somethings funky with 3.0.

hats almost kind of reassuring that its 3.0 and that it could be fixed with an update
it must either be push notifications, or maybe because sfari keeps pages loaded now this drains battery?
Yeah i hope its fixed soon, its sucks having to go back to 2.2.1, i was loving the landscape sms.
I am still working on my 11 month old 3G. With 3.0 software, my battery life improved greatly. Like night and day different. Previously, my outlook push email would just drain the battery down in a couple of hours. The phone would actually get hot. So, I had been on the check it every 15 min setting. Went back to push with 3.0 and it's been great. I've been using the phone on and off since 7am today and it's been almost 11.5 hours and I'm still at 81%. Before 3.0, I'd be looking for a charger in a few hours.
same here. strange thing is i ran push for the past year with no issues. however a week or so back my 3g started draining dead in just 2-3 hours and was always warm. same thing happened on my 3gs. so i set both to fetch and now the battery lasts much longer. haven't timed it, but probably can go a day without charging and light usage. because this never happened in the past with the push setting i'm wondering if it's something on the server side or exchange acct.
I was about to say "NO F..KING WAY" and then I saw that your brightness was at 25%. At that level, the iPhone is only usable in a cave!
I get used to it pretty quick, really, though I might bump it up to 30%
Up to 4h 12m usage, 2d 7h standby, and it is reporting 26%. I can't complain on that.
I've been having some really strange issues with the battery. First time it just drained really fast, like a few hours from full charge to dead. Granted I was using the video recording app heavily so I just assumed it was that. Then I noticed I had 1 bar signal. apparently I'm in a 3g dark zone. Turned off 3g and had 4 bars.
Second issue was more weird. I was going through the day and it was maybe 60% or so (mine doesn't show a percentage) and then suddenly it shut down from low battery. Once I got home to plug it back in it took several minutes before it finally booted and then took a while to charge.
I'm still just thinking this is a new battery issue and after a week or so of use things should settle down some. Also may do a full restore and not use backup. The initial restore I used on 3gs was from a 2g, which may be causing some weirdness.

was just going to edit previous post but then this came up:
So I found the place to enable the battery percentage. Turned it on and it said 56%. Then about 4 or 5 seconds from turning it on it jumped to 92%. Something really strange is happening here... Still hoping it will "learn" and settle down, don't want to do a full restore and lose the progress on a few games
*edit
I just got a txt message, and when I looked at the battery it said 49%. Usage is 55 mins and 2:23 standby. Tried to turn on and off the battery percentage and it didn't jump up again.

Mine drains quickly too.
What I dont understand is why some of the the reviews that I have read of the 3G S have claimed to have such great battery life. For example, the "quick look" that Tomshardware did after they got their phone on Friday claimed that after 3 hours of constant 3G internet use, their battery was down only 25%.
Yet, mine sometimes drains visibly. For instance, tonite I drove approximately 1.5 miles to pick up a pizza for dinner. I had Google Maps open and was watching the route get tracked with the GPS. From my house to the pizza place, my battery went from 45% to 40%. WTF???? In like 4 minutes? Thats Absurd.
I am removing everything from my phone tonite....my email...all my music..all my apps....etc...and restoring it. I am wondering if something was screwed up when I initially set it up - from my most recent backup like the instructions recommended.
Otherwise I am going to stop by the Apple Store next week if they have phones and ask for a new one. This is ridiculous. But next, after I restore this, I will put a movie on, and see how long the battery lasts playing video...if it lasts the 10 hours that Apple claims the battery should last with video then its ok. Otherwise its off to Apple.

I am experiencing something very similar to this with my new 3GS. If I use a simple app or browse the web, I can watch the battery count down, seemingly 1% per minute or so. Last night I had about half a battery bar left (this was before I turned on the numerical indicator) and when I woke up it was a red sliver. This was about 10 hours, I suppose, but the phone was just sitting there. I have also found that the phone warms up from just minor activity and can get pretty warm.
I do have location services and bluetooth on, but wifi off. I turned push email off tonight but it doesn't seem to have changed anything. I am curious as to what other people see when they try resetting the phone.
if your battery life is not longer than your 3g then you need to get your phone replaced! i love my 3gs it's so much faster and the battery life is awesome the only thing i noticed was a small scratch in the middle of the screen i will contact apple tomorrow to see if i can get the phone replaced for a new one
My battery life is excellent. Last night, I had 51% battery life left ater almost 6 hours usage. I watched a movie and a Simpsons episode plus about an hour of music and some phone calls.
This morning I woke up with 40% left after 24 hours and I recharged it because I had to leave.
Loving the 3G S battery life!
Oh, I keep everything on, push email / contacts and calendar on, 3G and wifi on, location services on and notifications off.

Then why does Apple themselves say to fully discharge your 3G at least once a month?
as an update to my previous posts the battery meter has smoothed out considerably. I've been using it to 40-50% then charging it. I still see the occasional jump, one I remember was 58% to 95% and then moments later back to 57%. I haven't had a 60% to shut-down-because-i-don't-think-i-have-any-more-juice again though.
So if you're having a problem try working the battery some. don't keep going from 100% to 0% to 100%. just get it down to under 50% each time you charge and see if it helps.

Has anyone checked their phone app? Mine shows the network is in use when i enter the phone app even if I am not using the phone at all (no calls, no voicemail checking). It remains in use (spinning indicator next to 3G at top of screen) as long as I stay in the phone app. Could this be part of the problem?
According to previous similar threads on here, the power management circuits in the iPhone (& iPod etc) turn the device off before the battery is truly flat, thus avoiding the possibility of damaging the cells. AFAIK the purpose of draining it once a month is to calibrate the battery, just like they advise you to do with their laptops.
My first iPhone, but here's where I'm at right now with battery:
Here's where I'm at today:
Push off; Fetch every 1 hour
WiFi off (at work)
3G on
Location services on
Roaming off
Brightness somewhere between 1/3 to 1/2
Usage: 3 hrs 41 min
This is reading a few emails; 1 call about 5 min.; 2 Speedtest checks; mostly music via wired headphones
Standby: 9 hrs 48 min
68%
